Hi Guys Does anyone know what is the meaning of this error and how to fix this... this appears when i try to launch the unreal engine 4.12


When posting for help try to include a bit more info.

What operating system and version are you using? Have you run unreal before? Is it only 4.12 that does not work?

Also a cursory google search for the start of that error leads to quite a few results, which ones have you tried?
